Product Description:
The IKG4015 cable is produced by Bosch Rexroth Indramat for the IKG Motor Power Cables series. It serves as a combined motor supply and low-level control link in industrial automation, carrying three-phase power and auxiliary control signals between a drive and its servo actuator. By integrating both circuits into one assembly, the cable simplifies routing through drag chains and control cabinets while maintaining electrical separation that preserves signal integrity. The design supports both fixed and dynamic machine sections, so it suits stationary cabinets and continuously moving axes alike.
The power circuit uses a conductor set of 4 × 1.0 mm², providing a current path sized for typical low-to-medium-power servo motors. Two twisted-pair control elements with a conductor arrangement of 2 × (2 × 0.75 mm²) run in parallel for brake-release or sensor-supply tasks. Copper resistance is limited to 19.5 Ω/km at 20 °C, supporting acceptable voltage drop over long machine runs. A tough PUR outer jacket resists abrasion, oil, and coolant, allowing installation in harsh production cells. The power cores withstand up to 300/500 V, while the control pairs are rated for 300/300 V, maintaining separation between safety extra-low-voltage circuits and the motor feed. For static routing, the cable can be bent to a minimum radius of 5 × D without causing conductor fatigue. Mutual capacitance remains 0.6 nF/m, supporting predictable drive behavior.
During operation, the conductors may reach 90 °C in fixed routing or 80 °C under continuous flexing, allowing thermal derating to be applied according to the installation method. Dynamic carriers require a minimum bend radius of 7.5 × D, which minimizes conductor stress when the cable cycles millions of times. An overall diameter of 12.0 mm fits common metric gland plates and energy-chain separators without requiring special adapters.
